Description

The invention relates to the field of air conditioners, in particular to an air conditioner indoor unit and an air outlet adjusting method thereof.
Background
After the existing embedded air-conditioning indoor unit is installed, the structure and the position of an air outlet are completely and basically fixed, for example, an air inlet grid and an air outlet of the embedded air-conditioning indoor unit are both arranged at the bottom of a machine body, wherein the air inlet grid is arranged in the middle of the bottom, and the air outlet is arranged in the circumferential direction of the bottom. The process of refrigerating/heating of the indoor unit of the air conditioner comprises the following steps: after air in the indoor space enters the machine body from the air inlet grid for cooling/heating/dehumidifying, the air is discharged out of the machine body from the fixed air outlet and enters the indoor space again. The air supply direction of the whole machine is relatively fixed.
Aiming at the scheme that the air outlet of the existing air-conditioning indoor unit is relatively fixed, the air-conditioning indoor unit with an improved air outlet structure appears on the market. As patent (CN204388229U) discloses a built-in air conditioner, which comprises: the air conditioner comprises a shell, wherein an air inlet and an air outlet are formed in the shell, the air outlet is arranged around the air inlet, and the air outlet comprises a main air outlet and an auxiliary air outlet communicated with the main air outlet; the air inlet grille is arranged on the shell and is positioned at the air inlet; the air deflector is arranged on the outer side of the air inlet grille and is positioned at the main air outlet; and the cover plate is arranged on the shell, and the auxiliary air outlet is limited between the cover plate and the shell. In the scheme, the auxiliary air outlet is used as a supplement of the main air outlet and is mainly used for eliminating air supply dead angles which are not in the air supply range of the main air outlet. That is, the above improvement of the scheme is to add a new air supply form mainly by introducing a new component, and the improvement of the new air supply form on the whole air supply amount and the air supply direction is very limited.
Accordingly, there is a need in the art for a new outlet adjustment solution to solve the above problems.
Disclosure of Invention
In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the air output and the air supply direction of the air outlet of the existing indoor unit of an air conditioner are to be further improved, the present invention provides an air outlet adjusting method of an indoor unit of an air conditioner, on one hand, the indoor unit of an air conditioner includes a unit body and a panel frame arranged at the bottom of the unit body, a fixed air outlet structure is arranged on the panel frame, a movable air outlet structure capable of stretching between a highest stroke point and a lowest stroke point along the axial direction of the unit body is arranged in the unit body, the fixed air outlet structure and the movable air outlet structure form the air outlet of the indoor unit of the air conditioner: under the condition that the indoor unit of the air conditioner is in a heating working condition, acquiring an ambient temperature and comparing the ambient temperature with a preset threshold value; and determining the axial position and/or the movement posture of the movable air outlet structure along the machine body according to the comparison result.
The invention realizes the change of the air output and the air supply direction of the air outlet through the axial extension of the movable air outlet structure along the machine body. Particularly, the change of air supply volume and air supply direction has been realized through same air outlet, makes the air supply scope of air outlet can adjust in a flexible way. The highest stroke point and the lowest stroke point are points capable of representing the highest position and the lowest position of the movable air outlet along the axial direction of the machine body, such as but not limited to: the highest stroke point and the lowest stroke point are respectively the intersection points of the movable air outlet and the axis of the machine body when the movable air outlet is at the highest position and the lowest position along the axial direction of the machine body. Preferably, the movable air outlet structure is substantially flush with the fixed air outlet structure at the highest stroke point.
In the process that the movable air outlet structure moves upwards from the lowest position, namely the lowest point of the stroke, to the highest position, namely the highest point of the stroke, the air supply amount of the air outlet can be reduced, the boundaries of the air outlet on the radial outer side and the radial inner side can be reduced, and particularly the air direction of the part close to the radial inner side can be gradually changed from steep to moderate, so that the problem of dead angles of air supply can be solved in a certain range according to different air supply requirements. And along with the removal of activity air-out structure, to same target windward point, even do not belong to the air supply dead angle from beginning to end, the air supply direction also changes, consequently can satisfy diversified air supply demand. The adjusting mode of the movable air outlet structure is determined through the ambient temperature, so that the air output of the air outlet and the air supply mode can be adjusted to better meet the real air supply requirement of a user, the user experience is improved, and the overall air outlet performance is improved.
In a preferred embodiment of the above-mentioned air outlet adjusting method, the step of "determining the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body according to the comparison result" includes: when the difference value between the preset threshold value and the ambient temperature is larger than a first preset value, the indoor unit of the air conditioner is enabled to operate in a first air outlet mode; and the first air outlet mode is that the movable air outlet is continuously positioned at the position corresponding to the highest stroke point.
The hot air flow mainly comprises relatively steep hot air flow and relatively gentle hot air flow. Wherein steep hot air flow is directly blown to the ground and gentle hot air flow is blown to the lower part of the cold air above the indoor space. Since hot air is less dense than cold air, the hot gas flow will necessarily rise. The steep hot air flow heats cold air on all layers in the indoor space in the rising process, the gentle air flow only heats the cold air on the upper layer in the indoor space, and heat obtained by the air close to the air outlet in the indoor space after heat exchange is slowly and gradually diffused to enable the indoor space to integrally realize heating. In the case where the movable outlet is continuously located at the position corresponding to the highest stroke point (hereinafter referred to as state a), the heating requirement is the highest, so that the required air supply amount is as large as possible and the hot air flow includes as large a steep hot air flow as possible. Through such air-out adjustment mode, the air supply volume is maximized and the part of the air supply volume close to the radial inner side has steep hot air flow with a larger proportion, thereby the air in the indoor space can be heated quickly and comprehensively.
In a preferred embodiment of the above-mentioned air outlet adjusting method, the step of "determining the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body according to the comparison result" includes: when the difference value between the preset threshold and the ambient temperature is greater than a second preset value and less than or equal to the first preset value, enabling the indoor unit of the air conditioner to operate in a second air outlet mode; and the second air outlet mode is that the movable air outlet reciprocates between the highest stroke point and a boundary stroke point below the highest stroke point.
In a preferred embodiment of the above-mentioned air outlet adjusting method, the step of "determining the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body according to the comparison result" includes: when the difference value between the preset threshold and the ambient temperature is greater than a third preset value and less than or equal to the second preset value, enabling the indoor unit of the air conditioner to operate in a third air outlet mode; and the third air outlet mode is to enable the movable air outlet to be continuously positioned at a position corresponding to the demarcation travel point.
In the case where the movable outlet is continuously located at the position corresponding to the dividing travel point (hereinafter referred to as state C), the heating demand is reduced but still large. In the case where the movable outlet is reciprocated between the highest trip point and the dividing trip point (hereinafter referred to as state B), the heating requirement is between state a and state C. In the state C, the blowing range is still large although it is reduced, but at this time, the blowing direction is adjusted, and specifically, the portion of the steep airflow on the radially outer side tends to be gentle. That is, in the state C, the total amount of the hot airflow is decreased and the ratio of the smooth hot airflow is increased, so that the total amount of heat obtained from the indoor space is decreased, and the period of time for which the heat is uniformly diffused to the indoor space, that is, the achievement period of the heating demand is increased. Compared with the state C, the air supply amount in the state B and the steep air flow proportion are both between the state A and the state C, and the diffusion of hot air flow after being sent into the indoor space is increased through the reciprocating motion of the movable air outlet structure. And for the same target windward point, the air supply directions at different moments are different, so that the heat diffusion in the indoor space is promoted through the collision and superposition of hot air flows in different directions at different moments.
Through setting up of boundary stroke point, can refine the stroke control of activity air-out structure under the different air-out modes better. For the same target windward point, the downward movement of the boundary travel point can reduce the air supply quantity of hot air flow obtained in the (second and third) air outlet modes (corresponding to the states B and C) and make the air supply direction become gentle; the upward movement of the boundary travel point will increase the amount of hot air flow obtained in the (second and third) air outlet modes, and the air supply direction will become steep.
In a preferred embodiment of the above-mentioned air outlet adjusting method, the step of "determining the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body according to the comparison result" includes: when the difference value between the preset threshold and the ambient temperature is greater than a fourth preset value and less than or equal to the third preset value, enabling the indoor unit of the air conditioner to operate in a fourth air outlet mode; and the fourth air outlet mode is that the movable air outlet reciprocates between the lowest stroke point and the highest stroke point.
In a preferred embodiment of the above-mentioned air outlet adjusting method, the step of "determining the position and/or the movement posture of the movable air outlet structure along the axial direction of the machine body according to the comparison result" includes: when the difference value between the preset threshold and the ambient temperature is less than or equal to the fourth preset value, enabling the indoor unit of the air conditioner to operate in a fifth air outlet mode; and the fifth air outlet mode is to enable the movable air outlet to be continuously located at the position corresponding to the lowest stroke point.
In the case where the movable outlet is continuously located at the position corresponding to the lowest travel point (hereinafter referred to as state E), the heating demand is the lowest. In the case where the movable outlet is reciprocated between the highest and lowest travel points (hereinafter referred to as state D), the heating demand is greater than the state E. In the state E, only a small amount of relatively gentle hot air is required to blow to the lower part of the cold air close to the upper layer of the indoor space first and heat the cold air in the rising process, and then the obtained heat is slowly and gradually diffused, so that the whole indoor space meets the heating requirement of a smaller amplitude (the total heat is relatively low, and the achievement duration of the heating requirement is relatively long). Compared with the state E, the air supply quantity and the steep air flow proportion of the state D are both larger than those of the state E, and the air supply quantity and the steep air flow proportion of the movable air outlet are both smaller than those of the state C in the stage of reciprocating motion between the demarcation stroke point and the highest stroke point. The diffusion of hot air flow after being sent into the indoor space is increased through the reciprocating motion of the movable air outlet structure in the maximum stroke range. And for the same target windward point, the air supply directions at different moments are different, so that the heat diffusion in the indoor space is promoted through the collision and superposition of hot air flows in different directions at different moments. However, since the range of the reciprocating stroke at this time is large, the degree of such collision and superimposition also varies greatly, and specifically, the average severity level of collision and superimposition is reduced as compared with the above-described state B, and therefore the overall heating demand is smaller than in the state B.
In a preferred embodiment of the above-described wind outlet adjustment method, an absolute value of a difference between a distance between the maximum stroke point and the boundary stroke point and a distance between the boundary stroke point and the minimum stroke point is not greater than 1/5 of a distance between the maximum stroke point and the minimum stroke point.
In a preferred embodiment of the above-described ventilation adjusting method, a distance between the maximum stroke point and the division stroke point is equal to a distance between the division stroke point and the minimum stroke point.
After the demarcation trip point is positioned near the middle point of the highest trip point and the lowest trip point, the difference between different modes is more obvious from the perspective of a user, so that the mode is more meaningful to distinguish, and the heating demands of different degrees, which are closer to the expectation of the user, can be provided more. Preferably, the dividing travel point is above the midpoint, so that the user's demand can be met in situations where the heating demand is large.
In a preferred technical solution of the above-mentioned outlet air adjusting method, the indoor unit of an air conditioner includes an outlet air motor that supplies air to the outlet, and the outlet air adjusting method further includes, before, simultaneously with, or after "determining the position and/or the movement posture of the movable outlet air structure along the axial direction of the machine body according to the comparison result", the following steps: and determining the operation parameters of the air outlet motor.
For example, the operation parameters may include, but are not limited to, the rotation speed of the wind outlet motor, the angular acceleration, the air supply time at the corresponding rotation speed and angular acceleration, and the like. Through adjusting the operating parameter to the air-out motor, can adjust the air output on the basis of the aforesaid adjusting the air outlet. For example, for the same target windward point, under the condition that other conditions are not changed, when the rotating speed of the wind outlet motor is increased by changing the frequency of the wind outlet motor, the air output in the unit time is increased, and therefore the target windward point can have more obvious heat feeling. For example, the rotating speed of the air outlet motor may be increased as the heating requirement increases, and the rotating speed in each air outlet mode may be equal or unequal. It can be understood that the air supply amount can be more flexibly adjusted for different air outlet modes on the premise of not deviating from the heating requirement.
The invention provides an air conditioner indoor unit, which comprises a control unit, wherein the control unit is used for executing the air outlet adjusting method in any one of the schemes. The air conditioner indoor unit has all the technical effects of the air outlet adjusting method, and the details are not repeated herein.

The support column 4221 comprises a cylindrical end that can freely slide in the arcuate track and a snap cap that prevents the support column 4221 from falling out of the arcuate track. As shown in fig. 5, the connecting member 43 is a cylindrical structure with one side closed, and the whole structure is similar to a bottle cap. The circumferential wall of the cylindrical structure is correspondingly provided with a spiral upward rail 431 which allows the support column 4221 to freely slide and allows the support column 4221 to freely slide in a surrounding manner, the position of the circumferential wall of the cylindrical structure close to the lower side is horizontally provided with a rack 432 which is used for being matched with the driving part in a surrounding manner, the lower side of the cylindrical structure radially extends outwards to form a flanging, and the flanging is provided with a plurality of notches 433.

Specifically, align the buckle and get into the breach, then rotate the connecting element gently and can install the connecting element to fixed air-out structure. After the installation is finished, the flanging of the tubular structure can freely rotate in the annular sliding groove formed by the fixed air outlet structure and the buckle of the L-shaped structure. As shown in fig. 6, the driving portion 5 includes an air supply motor 51 fixed relative to the machine body 1, for example, the air supply motor 51 is fixed on a fixed air outlet structure 41 fixedly connected to the machine body 1, specifically, referring to fig. 3, at a mounting position 412 disposed on the fixed air outlet structure 41. The output shaft of the blower motor 51 is connected to a gear 52, and the gear 52 is engaged with a rack 432 horizontally provided around the circumferential wall of the connecting member 43.
Preferably, the rail is an arc rail, and the height of the arc rail is determined according to the expansion and contraction amount of the movable air outlet structure 42. Specifically, when the support column 4221 is at the highest point of the arc-shaped track, the movable air outlet structure 42 should be retracted to a position approximately flush with the bottom of the fixed air outlet structure 41, and when the support column is at the lowest point of the arc-shaped track, the movable air outlet structure 42 should be at a position corresponding to the lowest stroke point. In order to ensure that the supporting columns can be reliably positioned at the highest point and the lowest point of the arc-shaped track, the two ends of the arc-shaped track are provided with clamping structures which can enable the supporting columns 4221 to be kept, such as planes cut on the arc-shaped track. In order to ensure that the support column can stay at a position corresponding to the decomposition stroke point, a clamping groove can be arranged at the position, namely, the support column 4221 can enter and be positioned in the clamping groove when ascending or descending to reach the position until external force is applied to make the support column slide out of the clamping groove.
In an assembled state, the ring sleeve 422 of the movable air outlet structure 42 is sleeved in the cylindrical structure, the cylindrical end of the support column 4221 on the ring sleeve 422 is located in the arc-shaped track, and the clamping cap of the support column 4221 extends out of the arc-shaped track. The connecting member 43 is connected to the fixed air outlet structure 41 through the matching of the flange and the buckle 411, and the connecting member 43 can rotate relative to the fixed air outlet structure 41. The movable air outlet structure 42 is connected with the connecting member 43 of the cylindrical structure through the matching of the support column 4221 and the arc-shaped rail, and the movable air outlet structure 42 is enabled to spirally ascend/descend along the axial direction of the cylindrical structure through the sliding of the support column 4221 in the arc-shaped rail, so that the expansion and contraction along the axial direction of the machine body are realized. In other words, in the rotation process of the connecting member 43, the movable air outlet structure 42 is axially extended and retracted relative to the fixed air outlet structure 41 by the sliding of the support column 4221 in the arc-shaped track.
With continued reference to fig. 3 and 4, in the present embodiment, two symmetrical mounting positions 412 are provided on the fixed air outlet structure 41, and two air supply motors 51 are fixed to the mounting positions 412.

The ring sleeve 422 of the movable air outlet structure 42 is circumferentially provided with four support columns 4221, and correspondingly, the connecting member 43 is provided with four arc-shaped rails, so that the force transmission process is more reliable through uniform distribution of circumferential stress. It can be understood by those skilled in the art that the above-mentioned arrangement is only an example, and can be flexibly adjusted according to actual conditions, as long as the stability and reliability of power output and power transmission are ensured, such as three support columns and the like.
In the air conditioner indoor unit, the process of power transmission of the movable air outlet structure when the movable air outlet structure realizes the telescopic motion of the movable air outlet structure is as follows: the air supply motor 51 rotates, and power is transmitted to the connecting component 43 with a cylindrical structure through a gear/rack pair, so that the connecting component 43 rotates relative to the fixed air outlet structure 41; the connecting member 43 transmits power to the movable air outlet structure 42 through the matching of the supporting columns and the arc-shaped rails, and the movable air outlet structure 42 extends out or retracts into the connecting member 43 in the rotating process through the forward rotation and the reverse rotation of the air supply motor 51, so that the movable air outlet structure 42 finally presents a movement form of telescopic movement relative to the fixed air outlet structure 41. By adjusting the frequency of the blower motor 51, the rotational speed, angular acceleration, and air blowing time at a certain rotational speed and/or angular acceleration can be adjusted, thereby refining control of the air blowing direction and air blowing amount, and optimizing the air blowing performance of the indoor unit of the air conditioner.
Referring to fig. 7, fig. 7 is a schematic flow chart illustrating an air outlet adjusting method of an air conditioner indoor unit according to an embodiment of the present invention. As shown in fig. 7, the air outlet adjusting method of the present invention mainly includes the following steps:
and under the condition that the indoor unit of the air conditioner is in a heating working condition, acquiring the ambient temperature and comparing the difference value between the preset threshold value and the ambient temperature. For example, the predetermined threshold is a higher temperature value (relative to the ambient temperature in a colder room), and illustratively, the predetermined threshold is 26 ℃ which is more comfortable for human body. And under the condition that the difference value between the preset threshold and the ambient temperature is greater than a first preset value, the indoor unit of the air conditioner operates in a first air outlet mode to ensure the maximum heating requirement. The first air outlet mode is that the movable air outlet is continuously located at a position corresponding to the highest stroke point.
And when the difference value between the preset threshold value and the ambient temperature is greater than a second preset value and less than or equal to a first preset value, the indoor unit of the air conditioner operates in a second air outlet mode to ensure the next largest heating requirement. The second air outlet mode is that the movable air outlet reciprocates between the highest stroke point and the boundary stroke point.
And under the condition that the difference value between the preset threshold and the ambient temperature is greater than a third preset value and less than or equal to a second preset value, the indoor unit of the air conditioner operates in a third air outlet mode to ensure medium heating requirements. And the third air outlet mode is to enable the movable air outlet to be continuously positioned at a position corresponding to the demarcation travel point.
And under the condition that the difference value between the preset threshold and the ambient temperature is greater than a fourth preset value and less than or equal to a third preset value, the indoor unit of the air conditioner operates in a fourth air outlet mode to ensure smaller heating requirement. The fourth air outlet mode is that the movable air outlet reciprocates between the lowest stroke point and the highest stroke point, namely within the maximum stroke range.
And under the condition that the difference value between the preset threshold and the ambient temperature is less than or equal to a fourth preset value, the indoor unit of the air conditioner operates in a fifth air outlet mode to ensure the minimum heating requirement. And the fifth air outlet mode is to enable the movable air outlet to be continuously located at a position corresponding to the lowest stroke point.
Preferably, on the basis of adjusting the air outlet, the air supply parameters can be adjusted, for example, the rotation speed of the air supply motor is increased under the condition that the heating demand is larger. And the rotating speed of the air supply motor is reduced under the condition that the heating demand is smaller. For example, the blower motor is maintained at a higher speed for medium or lower heating demand, and at a middle or lower speed for medium or lower heating demand. Of course, different air supply parameters can be configured for the air supply motor according to each air outlet mode.

When the movable air outlet structure 42 is continuously located at this position, the state a of the present invention, i.e. the state with the largest heating requirement, corresponds to this position.
As shown in fig. 8B, when the movable air outlet structure 42 partially extends out of the fixed air outlet structure and particularly extends out to a position corresponding to the division stroke point, the shape of the air outlet is changed so that the air supply amount and the air supply direction have the following characteristics: the proportion of the gentle airflow in the hot airflow sent to the indoor space is increased, and the proportion of the steep airflow is reduced. When the movable air outlet structure 42 is continuously located at this position, the state C of the present invention, i.e. the state with the largest heating requirement, corresponds to this position.

When the movable air outlet structure 42 is continuously located at this position, the state E of the present invention, i.e. the state with the minimum heating requirement, corresponds to this position.
When the movable air outlet structure 42 reciprocates between the lowest stroke point and the boundary stroke point, the state B of the present invention corresponds to this. When the movable air outlet structure 42 reciprocates between the highest stroke point and the lowest stroke point, i.e., within the maximum stroke range, the state D of the present invention corresponds thereto.
The air outlet of the air conditioner indoor unit is adjusted by the telescopic motion of the movable air outlet relative to the fixed air outlet along the axial direction of the air conditioner indoor unit, so that the air supply quantity and the air supply direction can be adjusted according to different heating requirements. The air outlet adjusting method adjusts the pose of the movable air outlet according to the environment temperature, and preferably adjusts the air supply parameter of the air supply motor on the basis of adjusting the pose of the movable air outlet, so that a user can obtain more reasonable heating requirements, and the air supply performance of the whole machine is optimized.
